IBOMA-MPEGA-DMAM共聚物的合成及其对酞菁蓝水性色浆的分散研究

文章导读

摘要以甲基丙烯酸异冰片酯(IBOMA)、聚乙二醇单甲醚丙烯酸酯(MPEGA)、N, N二甲基丙烯酰胺(DMAM)为单体,偶氮二异丁腈(AIBN)作引发剂,采用溶液自由聚合得到三元共聚物P(IBOMA-MPEGA-DMAM),并将其用于制备水性酞菁蓝色浆的分散体系。以色浆黏度为评价指标,通过中心复合法优化引发剂用量、反应温度和反应时间;采用FT-IR、¹H NMRGPC表征聚合物的化学结构和相对分子质量,并通过对水性酞菁蓝浆料的粒径、微观形貌、离心及冻融稳定性进行分析,考察了分散剂对酞菁蓝分散性影响。结果表明:当引发剂用量为2.12%,反应温度为81 ℃,反应时间5.3 h时分散性能较好且当分散剂用量3.6%时,浆料黏度为6.2 mPa·s,平均粒径为205 nm,与未添加分散剂、市售分散剂相比,用P(IBOMA-MPEGA-DMAM)分散剂制得的酞菁蓝浆料具有较好的分散稳定性。

Abstract： The terpolymer of P(IBOMA-MPEGA-DMAM) was obtained by solution free polymerization through free solution polymerization of isobornyl methacrylate (IBOMA), polyethylene glycol monomethyl ether acrylate (MPEGA) and,N, N-dimethacrylamide (DMAM), with azobisisobutyronitrile (AIBN) as initiator, and the terpolymer was applied to the aqueous phthalocyanine blue dispersion system. Taking the color paste viscosity as a main measurement index, the effects of the dosage of initiator, reaction temperature and reaction time on the dispersibility were optimized by central composite method. FT-IR and ¹H NMRGPC were used to characterize the chemical structure and molecular weight of polymers of the polymer. The particle size, microstructure, centrifugal and freeze-thaw stability of the aqueous phthalocyanine blue slurry were analyzed, and the influence of the dispersant on the dispersion of phthalocyanine blue was investigated. The results show that when the dosage amount of initiator is 2.12%, the reaction temperature is 81 ℃, the reaction time is 5.3 h, the dispersion performance is good, and when the amount of dispersant is 3.6%, the viscosity of the slurry is 6.2 mPa·s and the average particle size is 205 nm. Compared with commercial dispersants without added dispersants, the phthalocyanine blue slurry prepared by P(IBOMA-MPEGA-DMAM) has better dispersion stability.
